To all whom it may concern.-

Be it known that I,- CARL LANGER, manufacturing chemist, a subject of the King of Great Britain, residing at Ynyspenllwch, Clydach, in the county of Glamorgan, England, have invented certain new and useful Improvements in Apparatus for Obtaining Nickel from Nickel Carbonyl, of which the following is a specification.

.In specification to United States Letters Patent No. 606,843 is described apparatus for obtaining nickel from nickel carbonyl by passing the vapor of the latter through nickel in the form of shot or pellets kept at a tem perature of about 200 centigrade. The nickel deposits from the vapor on the shot, which gradually increase in size. For the proper working of the apparatus it is essential that the pellets should be as nearly as possible at the same temperature at all parts of the vessel containin them, which is preferably a cylinder. If t is is not the case, the nickel-carbonyl vapor may pass among the colder pellets without being decomposed, and nickel will be deposited on the hot surface of thecylinder. Moreover, the hotter pellets may decompose the carbon monoXid, causing a deposit of carbon on the nickel. Even when the cylinder is uniformly heated it not infrequently happens that owing to an increased rate of passage of the vapor or to a drop of the temperature of the pellets from some cause undecomposed vapor arrives at the outlets and, becoming heated in the neighborhood thereof, blocks them, causing a stoppage of the Working.

The present invention relates to improvements in the said a paratus whereby the temperature of the pe lets may be better controlled and made more uniform and danger of deposition of nickel about the outlets of the apparatus may be avoided. For these purposes each vessel or cylinder is heated by a number of gas-flames, preferably evenly distributed around the outside of the cylinder. The latter may be made with projections or ribs to form, with the outer casing, chambers to contain the as-jets. The part of each cylinder Where t e escape of gases occurs is formed as an annular chamber through which a cooling gas or liquid may be circulated, and the escape-pipe for the gases passes through the said chamber. In this manner the parts of the cylinder immediately I around the outlet are kept sufliciently cool to avoid decomposition of any nickel-carbonyl vapor which may escape.

he accompanying drawings illustrate one form of construction according to the invention.

Figure l is a vertical section of the a paratus wherein the nickel carbonyl is ecomposed. Fig. 2 is a vertical section of one of the cylinders of the apparatus drawn to an enlarged scale. Fig. 3 is a section on line 3 3 of Fig. 2 and Fig. 4 is a cross-section of the hollow ring which is placed between each cylinder and that next 1t.

A is a cylindrical vessel built up of cylinand a lower flange In buil ing up these cylinders to form t e vessel A a hollow rin w, having an inlet to and an outlet w is lai upon theupper flange f of the cylinder 0, which is to be the lowest, and on the top surface of this ring is supported the lower flange f of the next hi her cylinder 0, and so on. The innermost iameter of ring w is the same as the inner diameter of the upper part of cylinder 0, and there is a pipe m passing through the hollow ring, so that when the ring is in place it forms a hollow walled continuation of the cylinder 0', from which the pipe m forms an outlet. To kee a free passage within this continuation 0 cylinder 0, the lower end of the cylinder next above it is reduced in diameter to form a deflecting-surface a.

The cylinders c are cast with ribs 0 preferably in axial planes of the cylinder, as here shown, and these ribs form, with an outer cylindrical casin 0, chambers a, in each of which is a small gasurner b, supplied from a gaspipe 9, surroundin the cylinder. The top closure of the charm er a is a flan e h, perforated to form an outlet 1 for eac chamber. The space between the flanges h and f being also closed by the casing 0 forms a flue through which the products of combustion escape to the chimney 7c, Fig. 3. There is a space below the gas-pipe g for the sup ly of air to support the combustion of the allies of the burners b. A jacket 0 for receiving a non-conducting lagging is generally provided. The pi e s m open into a flue n common to them a l. The nickel carbonyl is assed into the vessel A by pipe y, which is o osed at its lower end and has outlets x, situated beneath ders 0, each of which has an u per flange f hoods z, which-prevent'= them :frombecoming;

As described in: the aforesaid s ecification the nickel pellets with which t e vessel is filled are kept in continuous movement by being removed from the bottom of thevessel b asuitab'le conveyer tandreinti'oduced into t e top of the vessel b a oonveyer v.
